Very smart and unique puzzle; I honestly couldn't get enough of this one. I wasn't expecting such a pleasant little head-scratcher. The simple pixel art looks great, and the retro vibe really brought me back to the old Game Boy days. The level design is excellent, with puzzles that rarely felt stale or repetitive, and that two-door room was absolutely maniacal, in the best way. My only critique is that it ended when it did, haha.
